Re: Engine misses and error code P1129
The VTEC (not Vtek) solenoid is easy to replace with the removal and reinstertion of a simple screw. From the RPM range that you are describing, it's more than likely that you car is VTEC-E (for economy) configured and not VTEC (for aggressive performance). The VTEC solenoid is cheap and is easily interchangeable with other units. Somehow, I don't feel as though your car is actually "missing" in the conventional sense. Try cleaning or changing the fuel injectors in sequence to see if that helps. What grade petrol are you using in your engine? Your K-series engine will be tuned for fuel economy instead of overall performance, so your VTC will also need to be checked as well.
